Dimensions Blue: directly from E-MIT-46 + E-MIT052 green: inferred from difference and/or photo red: uncertain. Need to verify with more photos 0.065 3.61 Proposal: position shutter off-center with respect to turret (using Vespel bushing) to provide additional clearance at L1 ‘snout’ 0.12 0.125 (guess / photo) girdle (new In 2002) 1.00 (photo) 3.10 0.50 (photo) 3.11 shutter 3.051 OD = 3.75 3.37+2*0.12 = 3.61 vs ID=3.63. So nominal clearance between button and shutter is 0.010”. ID = 3.63 0.06 (difference) clearance = 0.13 (difference) snout for L1 lens holder sticks out maybe 0.12-0.14 interference 0.10 – 0.12 (photo) 0.06 (photo + difference) 3.37 bottom lip (new in 2002) 0.18 0.128 (difference) 0.16-0.18 (photo / difference) Need to check this) 3.625
turret girdle L-1 lens to plasma shutter ‘elbow’ Is there value in adding a vertical ‘lip’ to ensure that shutter can’t be pulled away from the turret? Vespel SP-3 “L”-bushing
